RAILWAY. SIGNAL-FUSEE.

Specification of Letters Yet-ant,

Application filed May 5, 1914. Serial Ezo. 836.545.

To all whom it may concern Be-it known that 1, Bosnia M. CLARK, a citizen of the United States, residing at Newton Center, in the county of Middlese): and State of lllnssuchusetts, have invented Certain new and useful Improvements in Railway Signal-Fusions, of which the-fol-w lowing is e specification,reference being bad therein to the accompanying clrewin J My invention relates toimprovementsin railway signal fusees, and thepresent .invention pertains to an improved manner of securing a plug Within the end of the fuses tube, and it 18 more particularly intended for holding the plug which contains a spike.

It is well-known to those skilled'in the.

art that certain tubes of railway time burning signal fusecs contain at one end a spike through the mediu'mof which the fuses 1'. supported in an upright position burning, the spike being driven into a, rei-- -way tieor into the railroad bed; end it is also well-known to those sltilied in art that these spikes are carried by into the'wood plug, and bycom'oined glue "Band tacks construct the end of the fuses tube and the plug that the plug is firmly c nnected to and turnedwinwhrd to form a double wall.

Fig, 2 is a sectional view showing the completed fusee with the improved plug and double wall tube. Fig. 3 is a perspective view of the completed fuses.

-Referring now to the drawings in which like reference letters refer to similar ports,

'1 is a paper or fiber tube which contains the burning composition 2. This tube is composed, as usual, of a suitable grade of paper. '11: carrying out my invention. 1

The object of my present invention is to so provide one end of the tube with an inner annular shoulder or flange 3, which constitutes at that-end of the tube a double wall,

and preferably this double well is formed by turning backward and inward the tube itself, as clearly'show'n in Figs; 1 and -2. ilfhe plug to be used with this fish eel or shouldered end of the tube has a ho y-portic-n .4, oi. a size to fit within the opening at the iambic well end of the tube, as clearly shown in 2, and the inner end of the plug is provided with laterally extending Fntentcd Aug. 11', El ie.

shoulder or flange 5, which is prefcreblyf. though not necessarily, annular and unbroken, This flange 5 fits against the shoulder or flange formed by the doubie 3, and the composition 2 is against the inner end o'f the plug and serves to'hclol it permanently in position. 'lhose'slrilled in this ert know that in railway time bi'srning fl -SFJQS the composition 2, is tightly packed within the tube l so that the composition forms a substantial end solid support for the plug to prevent" it from being forced inward within the tuhe 1. This plug cara spike 6, when a spike is to be used, and. this invention is particularly intended for use with. a spiked lug. Freferebiy the double wall 5 is first iorrned on the tube 1' and the plug passed into the tube from the opposite end and pushed ther through until its flange 5 abuts against the inner end of,

the double wall 3. "'ihen the composition 2 is peeked within the. tube, However, 1'

wish it understood that the composition may be packed within the tube and then enough of it removed or drilled out of the tube to receive the plug, and then the well of the tube turned inward and forced down into the position shown 1n Fig. 52, by e,

suitably constructed rotating tool. The

plug may be formed of wood, metal, cement, or any other suitable material, Without cleparting from the spirit and scope of my present improvement. v

lihiie my invention is particularly intended for use in connection with rmiwug time burning signal fusees, I wish it understood thnt it may be used in connection. with fireworks, Where it is desired to support them in an. upright position through the medium of a plug. will also be understood that the spike 6, when the plug is of metal. is a nail cast within thethough t e nail may be cost or forme in- Eiug, llo

I we

tegraifwith' thei'plng whemthe plug is made of metal. 1

-' Havingthus described my invention, I CI-aimand desire to secure by Let- 5 texts-Patent is: 1,1;Aiz-wailway signal fusee, comprising an apex; tubelfhaying one end doubled inward .fiansinner wall, and a piug'having' p .at its inner end a flange fitting the interior 1g "of the paper tube and abutting a ainst theturned wall, the plug having a odyporzlppj-;extendin Within and fitting against p e 1111181 wal and a spike carried by the {plug-and projecting beyond the tube, for u the purpose described. K

J2. A railway signal 'fusee comprising a paper tubehaving one end doubled inward areiatively elongated double wall,

and 'a plug having an elongated portion embraced by and tightly fitting the said doua and abutting against the end of the; wall and the outer end of the plug carrying a projecting spike, and a signaling compound within the tube and abuttin against .the end of the plug, all combine for the pur pose described.

In testimony whereof I hereunto afiix my, signature in the presence of two it.v nesses.
